COMBINED TYPE-WRITING AND COMPUTING MACHINE.

Application and February 5, 1914. Serial No. 816,670.

To all whom it may concern:

Be it known that I, GUSTAVE O. Dnonxen, a citizen of the United States, residin in New York city, in the county of New ork and State of New York, have invented certain new and useful Improvements in (Tom bined Type-Writing and Computing Mu chines, of which thegollowing is a specifL cation. f

My invention relates to-a computing mnchine,.and is illustrated in connection 'with a combined typewriting and computing machine. Such machines usually include a gang of computing wheels forming a totalizer, and frequently include several such totalizers. The .amounts to which these wheels are turned to compute are usually determined by type-operating numeral keys.

In such machines it is often advantageous to cause the numbersas they are written to be added or subtracted at will. For this purpose many devices have been used, many of which are cumbersome or awkwardly placed for the operator. According to my piesent invention, controlling keys or levers for causing the computing wheels to add, subtract, or be neutral, are advanta ously placed near the computing keyboa For .exmmple, in a combined typewriting and computing machine the said controlling levers for the computing wheels may be placed adjacent the typewriter keyboard, and where there are several such levers, there -is preferably placed adjacent them a post or alining finger rest which serves to indicate at which position the levers stand, and serves as a convenient uide for the fingers in positioning said ever. \Vlmrc such a post is employed, the levers may bereadily placed by touch without requiring the attention of the eye of the operative.

My invention as herein disclosed is applied to a machine of the Underwood- 'right type, such as shown in my Patent No. 1,020,082, dated March 12, 1912. Said patent shows a gang of computing wheels engaged scriatim by a master wheel in a manner determined by the typewriter ca'rriage; said master wheel being powerdriven, and the amount of turning at every actuation thereof being determined by the typewriter keys. In said patent there are shown key-controlled power-driven devices which drive the master "wheel, and between said devices and the master wheel is inter posed a clutch which'may be set so as to cause said master wheel to turn the computing wheels to add, subtract, or be nontral. Said clutch is held set in any position by a detent, and, accordin to my invention, a lever for controlling said clutch may be placed just at the right of the Underwood typewriter keyboard, where it is convenient to the hand of the operative. may control this'clutch through a rock shaft and pitman. Where there is more than one totalizer, any additional totalizer may be controlled through a controlling lever which, like the other lever, is adjacent the typewriter keyboard, which second lever may be connected to a sleeve on said rock shaft. and from said sleeve may move the pitman connecting the appropriate clutch. in order to facilitatethe settiug-of said levers by the operative, and to assist in recognizing at a glance the points at which they stand. there may be advantageously placed near said levers a pillar or post which serves as a guide or rest for one finger of the operative, while another finger may be setting this lever or levers.

Other features and advantages will appear hereinafter.

and computing machine, showing only so much of the machine as is convenient for the purpose of illustrating my invention as applied thereto.

Fig. 2 is a sectional side view showing the. controlling levers and some adjacent parts.

In the Underwood-Wright machine. the usual ty ewriter platen carriage 1 carries a work-s eet (not shown herein) on which type (also not shown herein) are caused to print by numeral keys 2 and alphabet keys 3. As said keys thus print, they cause tho typewriter carriage 1 to be fed along a letter-space at every operation of a key. As the typewriter carriage travels along. it carries with it byan arm 4, a computing machine carriage 5 on which is ndjustably mounted a totalizer 6 comprising dial wheels 7. Said totalizer is thus conveniently placed for the eye of the operative.

\Vhcn in the adding zone. one of said dial -mounted 1n the totahzer 6. Said master wi l-cause the dial wheels wheel is fast on the usual shaft 10, said shaft being connected through a clutch'll of the usual kind to the usual drive shaft 12 of -the Underwood-Wright combined,

t writin and com utin machine.

ilhe clutih 11 is (if the usual kind em played in such machines and includes a bevel gear '13 fast on the master wheel shaft 10 said gear constantly meshing with two have gears 14 and 15 which run loosel on the shaft 12 but either of which may se zed thereto by a seizin 'member 16 slidably splined on the. sha t 12 and provided at each end with teeth 17 which mesh with similar teeth on each of the bevel gears 14 and 15. Said seizing member 16 may also occupy an intermediate position in which its teeth '17 fail to mcsh. with"either of the bevel gears 14 or 15, so that the clutch 11 may be said to occupy a neutral 'tion, because at this time the drive sha 12 has no efl'ect on the master wheelwhichever way it mayturn.

"When, however, the seizing member 16 en ages one of the bevel gears 14 or 15 it to turn in addin' direction, while when it engages the ot er, it will cause said wheels to turn in subtractin direction.

The ma the usual carry-over roll. 18 fast on its shaft 19, said carri over assisting roll, like the master whee being power driven, 4 driven by a drive shaft 20 which, like the shaft 12, is-always turned in one direction. In order to permit the ca -over shaft 19 to b reversed or be neutra whenever the master wheel shaft 10 is reversed or neutral, there is provided between the drive shaft 20 and the carry-over shaft 19-a clutch 21 like the clutch 11.

Said clutch 21 includes bevel rs.22 and 23 which are loose on the drive shaft 20 but are adapted to be clutched thereto bye clutching member 24 like the clutchiu member 16, and said gears when so utched thereto, like the. bevel ears 14 and 15, turn the carry-over shaft 1 in one direction or the other in a bevel gear (not shown herein) with which they are constantly in mesh. Said clutching member .24 may also occupy an intermediate position whenever the clutc ing member 16 occupies an intermediate position.

For causing the two clutches to be shifttcd to 'ether, there is rovided a lever 25 pivoted is, engaged by the yieldin no as shown also r The carry-over shaft 19 is thustion 44, the ed between its en 3 at 26, which lever carries at each end a pin 27 lying in a oove 28 in each of the clutching members 16 and 24. In order to allow for lost motion in case of any imperfect meshing of .the teeth onthe seizin inember 24 with the internal teeth on its vcl gears 22 and 23, the lever 25 is formed of two parts connected tfigether bya yielding spring The er part 30 of said ever, which part engages with the clutching member 24, is f rmedof an arm pivoted on the lever 25 a 31 and includes an arm 32, which arm sfimng 29, said spring always moving wit 1 t e lever 25 because it is firmly mounted in a pin 33 on said lever which in forms a' ivot on which thesmaller member 30 is pivoted.

In order to revent too much motion by .the yieldin o the spring 29, the smaller part 30 inc udes arms 34 -whiuh extend on either side of the head 35 of the pivot 26 on which the lever'25 is pivoted. The lever shaft carries at its outer end a disk 41,-to

which disk the itman 38 is pivoted.

The lever 39 by which the rock shaft 40 is turned includes a finger piece 42 and a bod 43, said body being formed as the bla e or late to which thefin er piece 42 ,is joined. y a bentportion.

of the lever 39 is extendul down beyond the rock shaft40 forming a broad plate porof the ortion 44 being 'cut into three'no cs 45, 4 47, which notches coo rate with a s ring detcnt wheel 48, 'sai v detent wheel being adapted to hold the lever39 in any position in which it is set. The detent wheel 48 is loosely pivoted on afreely swinging dctent arm 49, which arm is drawn up by a spring 50 to hold the wheel 48 engaged with any of the notches 45, 4c, 47.

The lever 39 is held against overthrow by the flat sides 51 of the end notches 45 and 47, which are extended downward so that they bear flat against the wheel -18 when he body 42 a said wheel is engaged with an end notch.
